FOLDING SEAT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 746,763, datedDecember 15, 1903. Application filed April 9, 1903. Serial No. 151,887.(No model.)

To all whom it may concern.-

Be it known that I, JOSEPHINE VAN BLAH- CUM, a citizen of the UnitedStates, residing at Puerto Cortes, in the Republic of Hon: duras, haveinvented a new and useful Folding Seat for Sewing-Machines, of which thefollowing is a specification.

This invention relates to an attachment for pedal-operated machines,such as sewing-machines, and more particularly to a folding seattherefor, and has for its object to provide a simple, inexpensive, andefficient device of this character, which may be quickly attached totheordinary sewing-machine and which may be adjusted vertically to anydesired height to accommodate the operator.

A further object of the invention is to provide a seat attachment, therelativedisposition of the several parts being such as to per mit thesame being compactly folded beneath the table of the sewing-machine whennot in use.

The invention consists in the construction and novel combination andarrangement'of parts hereinafterfully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended, itbeing understood that various changes in form, proportion, and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a side elevation of a sewing-machine,showing a folding seat constructed in accordance with my inventionapplied thereto. Fig. 2 is a front elevation of the same, showing theseat folded beneath the sewing-machine table; and Fig. 3 is a detailsectional view of the frame, treadle, and bearing-pin.

Similar numerals of reference indicate corresponding partsin all thefigures of the drawlugs.

l designates a sewing-machine of the ordinary form and construction, and2 my improved folding-seat attachment.

The folding seat 2 consistsof a 'standardor pedestal 3, havingoutwardly-extending legs or feet 4, the upper end of the pedestal beingthreaded, as shownat 5, and adapted to so gage the interior threads of acollar 6, se-

cured in any suitable manner, as by screws or like fastening devices, toa seat 7 and by means of which said seat may be adjusted vertically toany desiredheight to accommodate the operator. Pivoted to theoppositelydisposed laterally-extending legs or feet 4 of the pedestal 3by means of bolts or screws 8 are a pair of rods or lovers 9, whichextend upwardly and rearwardly, being pivoted to the side bars 10 of thesewing-machine frame by means of threaded pins 11, which pass throughends of the rods or levers and the side bars 10. The ends of the screwsare pointed or cone-shaped, as shown at 11, and fit incorrespondingly-shaped bearing-openings 1-2 in the sides of the treadle12, forming the pivotal point upon which said treadle oscillates whenthe machine is operated. Clamping-nuts 13, interposed between the sidebars l0 and the levers 9, engage the threaded section of'the screws 8,and by means of which said screws may be adjusted laterally and thelevers 9 secured in the desired position with relation to the frame. Therods or levers9 are each formed of two members hinged, as shown, at 14,which permitssaid levers to ;-be forced upwardly and the seat compactlyfolded beneath the stand of the machine when not in use, as clearlyshown in Fig. 1 of the drawings.

From the foregoing description the opera tion of my device will bereadily understood, and isas follows: The parts being in the positionshown in Fig. 1 of the drawings when it is desired to use theattachment, the operator grasps the seat and pulls outwardly anddownwardly thereon until the seat assumes a position slightly in advanceof the sewing-machine, when the lovers 9 will be extended to their fulllimit and further outward movement of the seat prevented. The seat maynow be adjusted vertically to any desired height to accommodate theoperator by revolving the seat on the threaded end of the pedestal. Whennot in use, the seatmay be compactly folded beneath the table or standof the machine by exerting a slight upward pressure on the rods orlevers 9, which causes said levers to be forced upwardly-and permits theseat to be folded within the lines of the frame, as clearly shown inFig. 1 of the drawings.

Having thus described my invention, what I claim, and desire to secureby Letters Patbeing provided with an intermediate hinged ent, isconnection to permit the levers being swung An attachment forsewing-machines, comupwardly and the seat folded within the lines 2prising a stool or seat, a pair of approxiof the frame. :5 matelyhorizontal levers one end of each of In testimony that I claim-theforegoing as which is pivoted to the seat at a point near my own I havehereto affixed my signaturein the floor-level and the opposite endthereof the presence of twowitnesses.
